Rents have been growing for a year but estate agents today said owners from Kensington to Canary Wharf are now cutting prices by hundreds of pounds. The owner of a house in Chelsea which was let last year for £2,700 a week is now taking offers for more than £2,000 according to Knight Frank. Tim Hyatt of Knight Frank said: "We have noticed a huge increase in stock in the last three to four months, while inquiries have increased only marginally."
